Considerations

Consider implementing this after streaming/continuous payments.
One-time payments should also be easier to implement once the continuous payment flow is complete.

Discussion point
Q: To discuss with Alex - does the one-time payment draw from the (monthly) budget already available, or not?
A: @raducristianpopa - To enhance UX, performing a one-time payment will deduct funds directly from the available (monthly) budget. This approach eliminates the need for an additional user action - approving a new grant.

Decision
alpha release: split once-off payments equally between the wallet addresses found on the website

Update on 30 Apr: the background functionality for once-off payments is working, but feedback to the user on the extension's pop-up that the payment was successful is, not implemented yet. We'll pick this up Tues, 7 May.
